Diagnosis. The forewings have an obtuse angle in the centre of the distal margin, and the margin of the hindwing is more or less straight, rendering it triangular. The colour is generally a medium purplish grey with diffusely darker fasciation, oblique on the forewing, the strongest fascia being in the basal half of the wing. There is a pale yellow spot near the apex of the hindwing.

Geographical range. Sri Lanka, Ryukyu Is. (Yoshimoto, 2001), Borneo.

Habitat preference. Four specimens have been taken in recent surveys, two from disturbed coastal and secondary forest at Mumong and Seria on the Brunei coast and one inland at 300m in the dipterocarp forest of the Ulu Temburong. The fourth is also from dipterocarp forest, at about 600m on the slopes of G. Kinabalu at Poring.
